Physics 2000: Resonance Feature Summary

A typical TV antenna such as this one (hi-res version) is a resonant system--the transverse arms are half a wavelength long at the frequencies of the traditional broadcast TV channels. The smaller sets of transverse arms are for higher frequency (UHF) channels. For more on resonance, see Standing Wave Resonance. To read about a new kind of antenna, visit Fractal Antenna Design.
